added missing strings to translation files (waterway in tunnels).
Still missing: adding the new signatures to other TYP files too (same: waterway in tunnels)
Adapted Version numbers for lines and polygon style files
BUGFIX: Enabled check if WORKDIR exists for fetch_osm and fetch_ele
Additional adaptions regarding waterways in tunnels and culverts: own linetype for each different waterway for being able to implement it in other TYP files too
- Added proper handling of waterways in tunnels also to other TYP files (before it was only in freizeit.TYP)
- added some whitespace to freizeit.txt to adopt new parts to existing parts
